METAL CASK 0R BARREL,

Specification of Letters Patent.

Patented July 12, 1am.

Application filed January 25, 1908. Serial No. 412,622.

To all whom it may concern:

Be it known that I, JOHN JACOB WoLr, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Metal. Oasks or- Barrels and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

y invention relates to certain new and useful improvements in metallic casks or barrels intended principally for the storing of ale, beer, and hke liquids, under pressure, and for preserving the temperature of the contents of the cask or barrel as against the higher temperature of the external atmosphere, so that a retail dealer, receiving the cask of ale or beer from thecooling room of the brewery and at the low temperature of storage, will be able to keep it at substantially that temperature, without the employment of ice, until its contents are fully dispensed.

In the accompanying drawing, Figure 1 represents a longitudinal section of a metallic cask or barrel embodying my improvements; Fig. 2 represents a transverse section thereof on a planeindicated by the line 2-2 of Fig. 1; Fig. 3 represents a section through one of the heads of the metallic cask or barrel on'a plane indicated by the line 3-3 of Fig. 1; Fig. 4 represents a detail View of one ofthe taps or bung-hole fittings inits relation to the adjacent parts of the metallic cask or barrel.

Similar letters of reference indicate similar parts throughout the several views.

Referring to the drawing, it will be noted that the inner chamber within which the beer or ale is to be contained consists'of a metallic cylinder a provided with inwardly flaring or dished heads 6, which are preferably welded, electrically or otherwise, to the cylinder a, so as to make a complete and absolute closure at their points of junction with the cylinder. The outer wall 0 of the cask or barrel consists of a like metallic cylinder, and between the inner cylinder a and outer cylinder 0 are interposed two cylinders d, 6, having corrugated walls, the corrugations being in contact respectively with the outer surface of the inner cylinder a and the inner surface of the outer cylinder 0. These intermediate corrugated cylinders, which are granulated dry cork it, or its equivalent,

which serves as an additional heat insulator around the entire periphery of the cask or barrel.

The top and bottom ends of the cylinders a, c, d and e are provided with cap pieces n of massive iron (preferably wrought-iron). These cap pieces not only form a rolling tread for the cask or barrel, but, being provided with annular flanges m as shown, they likewise serve to firmly unite the ends of the cylinders to each other and. tothemselves.

by means of .rivets 37, thereby stanch and reliable connection."

The heads of the metallic cask or barrel are likewise provided with insulating dead air spaces 8 and t by means of the dished corrugated plate o and the corrugated plate 41), with an intervening body of dry granulated cork h, as before. The outer surface of each head is made up. of a reversely flanged plate is and the rivets p which secure the caps 17. to the vertical cylinders likewise pass through the flange of this outer plate 7:, thereby securing the heads in place by the same means which unite the caps or treads to the vertical cylinders. v The bungfitting 1 and the tap and vent fittings as, e are inserted during the putting together 0 the parts of the vessel, and are adapted to receive the usual closing bungs or to s.

In orderto make water and air tlght the joint between the cap pieces or tread rings n and the surfaces which they overlap. I also prefer to form the tread rings at their side edges with 'small'flan es which I press inwardly and laterally, y hydraulic pressure or otherwise, into absolutel intimate contact with the edges of the anged plates is and outer cylinder 0.

Having thus described my invention, what I claim is:

1. In a metallic cask or barrel, a body portion comprising inner and outer cylinders, intermediate reinforcing cylinders located in the annular space between said making a first named cylinders and provided with reinforcing corrugations, and means at the upper and lower rims or edges of the barrel to which said intermediate cylinders are secured; substantially as described.

2. In a metallic cask-or barrel, the combination of inner and outer cylinders, intermediate cylinders located in the annular space between said first named cylinders, and means for securing both ends of said intermediate cylinders to the inner and outer cylinders at the upper and lower ed es or rims of the barrel; substantially as escribed.

3. In a metallic cask orbarrel, the combination of inner and outer cylinders, intermediate cylinders located in the annular space between said first named cylinders, and annular members at opposite ends of the barrel to which both ends of said intermediate cylinders are secured; substantially as described.

4:. In a metallic cask or barrel, the combination of inner and outer cylinders, intermediate reinforcing cylinders located in the annular space between said first named cylinders and substantially co-extensive with the latter, and a tread ring to which said reinforcing cylinders are secured; substantiallyas described.

5; In a metallic cask or barrel, the combination of inner and outer cylinders, intermediate cylinders located in the annular space between the first named cylinders and extending substantially throughout the height of the barrel, and a tread ring fitting over the ends of all of said cylinders and to which all of the same are attached; substantially as described.

6. In a metallic cask or barrel, thecombination of inner and outer cylinders, intermediate cylinders within the annular space between the first named cylinders and extending from the bottom of the barrel to the top thereof, and a tread ring having flanges to which all of said cylinders are riveted; substantially as described.

7. In a metallic cask or barrel, the combination of inner and outer cylinders, intermediate cylinders within the annular space between the first named cylinders and extending substantially throughout the height or length of the barrel, a tread ring havlng annular flanges against the outer faces of which the intermediatev cylinders lie, and means to secure said cylinders, and the inner and outer cylinders, to said flanges; substantially as described.

8. In a metallic cask or barrel, the combination of inner and outer cylinders, cylinders located within the annular space between the. first named cylinders and provided with reinforcing corrugations, and tread rings at the opposite ends of the barrel to which all of said cylinders are secured; substantially as described.

9. In a metallic cask or barrel, the combination of a main body portion embodying inner and outer cylinders, a tread ring having a portion fitting between said cylinders, a head-plate fitting within the inner. cylinder and having a circumferential flange, and rivets-which extend through said flange, the cylinders, and the tread ring and secure the parts together; substantially as described.

10. In a metallic cask or barrel, the combination of inner and. outer cylinders, intermediate cylinders located between the inner and outer cylinders, a tread ring having flanges entering the space between the intermediate cylinders and against the outer faces .of which said intermediate cylinders are seated, a head-plate having a circumferential flange resting against the inner cylinder, and rivets which pass through the cylinders and the flanges of the tread rin and head-plate; substantially as describe 11. In a metallic cask or barrel, a main or body portion comprising inner and outer cylinders, a tread ring, an inner head plate secured to the inner cylinder, an outer head plate secured to the tread ring, and plates in the hollow head formed by said head plates and forming dead air spaces therein; substantially as described.

In testimon whereof I aflix my signature, in presence 0 two witnesses.

It is hereby certified that in Letters Patent No. 964,080, granted July 12, 1910, upon thelapplication of John Jacob Wolf, of Philadelphia, Pennsylvania, for an improvement in Metal Gasks or Barrels, an error appears in the printed specification requiring correction, as follows: Page 1, line 100, after the word foverlap,

the period should be stricken out and a comma inserted instead; and that the said Letters Patent should be read with this correction therein that the same may- I conform to the record of the casein the Patent Oflioe.
